Dahlia Pot Tubers  

The tubers we offer are dahlias which have been grown for a full season in the confines of a 4” or 5” pot, so that a small compact tuber is produced. They are ideal material for the exhibitor with a heated greenhouse or propagator to enable their own propagation. Tubers are available from DECEMBER to FEBRUARY and are packed in polythene sleeves with vermiculite. We strongly advise unpacking on arrival and if necessary store tubers in a cool frost free environment until required for setting away. A minimum of 50F (10oC) is required for propagation, water sparingly until growth is evident. Should any tuber fail to have shown any signs of growth by the end of March then please contact us so we can aim to organise replacements as rooted cuttings. Please note Pot Tuber numbers are limited so order early to avoid disappointment.

Also available as mini plants and garden ready
